Summary description
The M25P20 is a 2 Mbit (256K x 8) Serial Flash Memory, with advanced write protection
mechanisms, accessed by a high speed SPI-compatible bus. The M25P20 features high
performance instructions allowing clock frequency operation up to 75 MHz
The memory can be programmed 1 to 256 bytes at a time, using the Page Program
instruction.
The memory is organized as 4 sectors, each containing 256 pages. Each page is 256 bytes
wide. Thus, the whole memory can be viewed as consisting of 1024 pages, or 262,144
bytes.
The whole memory can be erased using the Bulk Erase instruction, or a sector at a time,
using the Sector Erase instruction.
In order to meet environmental requirements, Numonyx offers these devices in ECOPACK®
packages. ECOPACK® packages are Lead-free and RoHS compliant. ECOPACK is an
Numonyx trademark. ECOPACK specifications are available at: www.Numonyx.com.
This datasheet details the functionality of the M25P20 devices, based on the previous T7Y
process or based on the current T9HX process (available since August 2008). The new
device in T9HX is completely backward compatible with the old one in T7Y and it additionaly
features:
- extended Vcc range (2.3-3.6V)
- improved max frequency (Fast Read) to 75 MHz in the standard Vcc range 2.7-3.6 V
- max frequency (Fast Read) of 40 MHz in the extended Vcc range 2.3-2.7V
- UID/CFD protection feature
Figure 1.
1. 75 MHz operation is available only on the VCC range 2.7 V - 3.6 V and for process technology T9HX devices,
identified by process identification digit "4" in the device marking and process letter "B" in the part number.
